PA50, 500 and 600 each have 2 audio outputs. Best you could do is assign bass and drums to left channel out, and right hand & accompaniment voices to right channel out. Depends on if you want a stereo mix.
You have to move up to PA800, PA2X, or PA3X (or down to PA80 or PA1x)) to get 4 assignable audio outputs.
